Yes. you should adjust your Mortgage Interest deduction to exclude the closing cost, that are rolled into the refinancing.
As per IRS publication 530, homebuyers may deduct certain closing costs when they file federal tax returns. These include the points, or loan origination fees, you paid, as well as property taxes and mortgage interest. The IRS considers points as prepaid interest, thereby permitting deductibility.
